A line lead mechanic reports about a common problem of spurious; intermittent rt outer tank low fuel temperature upper ECAM display messages which self-erase two minutes later on the airbus A318's; A319's and A320's. Replacement of the wing fuel temp sensor generally resolves the problem; but requires a wing fuel tank entry open-up procedure.

Narrative:
In reference to a log write-up; an A320 aircraft departed ZZZ and experienced a right wing outer tank low fuel temp upper ECAM display; which self-erased two minutes later. This aircraft has multiple hits with this same type of occurrence (referenced in deferral process as inf-information). I called maintenance control to confer if this recurring situation should not be addressed with a fuel tank entry [procedure]; with a probe change and sensor change; along with a possible wiring check at some time in the near future. We agreed that the existing situation with no message displayed was a deferrable condition; but something with this much history should be addressed soon. We agreed to make the deferral as was written by me; after the A320 arrival in ZZZ1; and requesting further crew comments should the condition occur prior to fix.
